In the third quarter of 2012, comScore reported quarterly revenue of $64.3 million, an increase of 9% over the third quarter of 2011. Revenue growth compared to the third quarter of 2011 was adversely affected by declines in the Company's advertising copy testing business and by foreign currency fluctuations. Excluding the Company's advertising copy testing business, which comScore is evaluating for potential divestiture, third quarter revenue measured on a non-GAAP pro forma basis would have increased 13% over the comparable period in 2011.

GAAP loss before income taxes was ($1.7) million and GAAP net loss was ($3.1) million in the third quarter of 2012. This represents a GAAP net loss of ($0.09) per basic and diluted share. Non-GAAP net loss was ($0.7) million, or ($0.02) per diluted share in the third quarter of 2012, compared to non-GAAP net income of $0.21 per diluted share in the third quarter of 2011. Adjusted EBITDA was $11.0 million, or 17% of revenue, as compared to adjusted EBITDA of $10.7 million in the third quarter of 2011. On a non-GAAP pro forma
basis that excludes the impact of the copy testing business, adjusted EBITDA increased 7% from a year ago. Reconciliations of the foregoing historical non-GAAP financial measures to the most closely applicable GAAP financial measures are included in the financial tables attached to this press release.

Dr. Magid Abraham, comScore's president and chief executive officer said, "We are pleased that our revenue and adjusted EBITDA results were above our guidance range for the third quarter, largely due to strength of our core product offerings and contributions from newer products such as validated Campaign Essentials (vCE) and Digital Analytix (DAx). We added 45 net new customers in the third quarter, bringing total customer count to 2,114, and our overall renewal rate continued to exceed 90% on a constant dollar basis."

"We are pleased with our sales momentum and marketplace reaction to our newer products. We recently launched vCE Video, for Video campaign measurement and verification, with endorsement from over 30 industry partners. In addition, we announced vCE Multi-Platform (MP), which represents a major milestone in cross-platform advertising measurement across TV, web and mobile platforms. Additionally, we launched a new website analytics module, DAx Monetization, which allows publishers to leverage viewability and duration data for improved ad placements on their website, in order to optimize viewable inventory and maximize monetization of advertising packages. These new capabilities position us well for the new cross media landscape and the increased industry focus on viewable advertising metrics as the basis for new digital ad currency. We believe that the combination of our strong client
renewal rates and a compelling portfolio of differentiated, globally available products should help drive healthy revenue growth and profitability over the longer term."

*Reconciliations of GAAP to non-GAAP measures are set forth in the attachments to this press release.

Due to the high variability and difficulty in predicting certain items that affect GAAP net income, such as tax rates and stock price, comScore is unable to provide a complete reconciliation of Adjusted EBITDA to net income (loss) on a forward-looking basis without unreasonable efforts. However, a reconciliation of forward-looking Adjusted EBITDA to GAAP income (loss) before income taxes is set forth in the attachments to this press release.

Given the recent discussion regarding our copy-testing business, we are also providing non-GAAP pro forma revenue and pro forma adjusted EBITDA guidance reconciliations that exclude this business in the attachments to this press release.

Conference Call Information:Management will provide commentary on the company's results in a conference call on Thursday, November 1, at 5:00 pm ET.

About comScore comScore, Inc. (NASDAQ: SCOR) is a global leader in measuring the digital world and preferred source of digital business analytics. For more information, please visit http://www.comscore.com/companyinfo.

Non-GAAP Financial MeasurescomScore reports all financial information required in accordance with generally accepted accounting principles (GAAP). comScore believes, however, that evaluating its ongoing operating results will be enhanced if it also discloses certain non-GAAP information because it is useful to understand comScore's performance, as it excludes non-cash and other charges that many investors believe may obscure comScore's on-going operating results.

In addition, comScore believes that adjusted EBITDA is a useful measure for investors to use to evaluate its operating performance. Adjusted EBITDA comprises non-GAAP net income further adjusted to exclude the cash tax provision, depreciation, interest income (expense) net, and costs not associated with ongoing operations, such as acquisition related, litigation and related settlement costs. A reconciliation of comScore's GAAP results to these non-GAAP measures is included in the financial tables accompanying this release.

The company believes that adjusted EBITDA is an important indicator of the company's operational strength and the performance of its business because it provides a link between profitability and operating cash flow. Adjusted EBITDA is also widely used by investors and analysts as a supplemental measure to evaluate the overall operating performance of companies in comScore's industry. comScore's management also uses adjusted EBITDA extensively as a measure of operating performance because it does not include the impact of items not directly resulting from its core operations. Moreover, the company's management uses the measure for planning purposes, to allocate resources and to evaluate the effectiveness of the company's business strategies and management's performance.

The company believes that excluding certain costs from non-GAAP net income and EPS and from adjusted EBITDA provides a meaningful indication to investors of the expected on-going operating performance of the company. Specifically as it relates to acquisitions and restructurings, the exclusion of these costs reflects the expected benefits realized or to be realized upon the integration of acquired entities into comScore, and the realized benefits of the restructurings.

comScore's management also uses free cash flow as a non-GAAP measure of the company's operating cash flow less cash expenditures for capital spending and acquisition-related costs as a key indicator of the company's operating cash flow performance.

Whenever comScore uses such historical non-GAAP financial measures, it provides a reconciliation of historical non-GAAP financial measures to the most closely applicable GAAP financial measure. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these historical non-GAAP financial measures to their most directly comparable GAAP financial measure included in the financial tables accompanying this release. Although the company provides a reconciliation of historical non-GAAP financial measures, due to the high variability and difficulty in predicting certain items that affect net income, such as tax rates and stock price, comScore is unable to provide a complete reconciliation of adjusted EBITDA to net income on a forward-looking basis without unreasonable efforts. However, a reconciliation of forward-looking adjusted EBITDA to GAAP income
(loss) before income taxes is set forth in the attachment to this press release.

These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. The use of certain non-GAAP financial measures requires management to make estimates and assumptions regarding amounts of assets and liabilities and the amounts of revenue and expense during the reporting periods. Significant estimates and assumptions are inherent in the analysis and the measurement of certain elements of non-GAAP financial measures such as the impact of purchase accounting on acquired deferred revenue and the amortization of deferred contract costs associated with acquired deferred revenue. comScore bases its estimates on historical experience and assumptions that it believes are reasonable. Actual results could
differ from those estimates.
